/**
*
CallReferenceNumber ::= OCTET STRING (SIZE (1..8)) 

The use of this parameter and the conditions for its presence are specified in 3GPP TS 23.078 [98] and 3GPP TS 23.079 [99].

This parameter gives the call reference number assigned to the call by the CCF. For encoding see
GSM 09.02 [20].

The CRN is an octet string with variable length between one and eight octets. An MSC uses an
internal counter to generate the CRN. Each CRN that is generated in an MSC is unique within that
MSC. For every call that is established in an MSC, a CRN is generated by that MSC. The CRN is
strictly associated with the MSC that allocates the CRN.
